Study On Storrage Technology For High Quality Paddy Of In Southern China Area

This paper selects 15 varieties of high quality paddy for the 2012 annual test food, set up to reconcile with nitrogen temperature 20 ℃, 25 ℃ temperature storage and other conventional air conditioning temperature and storage conditions, quality rice research in gas composition, temperature, moisture and other different storage conditions By quality changes, analyze the main factors affecting changes in the quality of high-quality rice, the longest shelf life quality rice obtained under different experimental conditions.After 2 years of tests showed that, under normal circumstances, high-quality rice storage period of one year and a half less than using conventional storage; to extend the storage period to two years, considering the economic costs and other factors, should adopt the temperature 25 ℃, Under storage. Research by nitrogen filling tune in real bins showed that large-scale real SQUAT rice warehouse inflated gas concentration within each test point distribution, and in summer the temperature is not aerated compartment for a greater change, can effectively kill dead insects inside the warehouse, nitrogen technology could delay its quality deterioration speed. While nitrogen than conventional grain storage grain storage deficiencies in economic, environmental and social benefits but the perspective of nitrogen storage of rice has great potential in southern China, is a practical real quality rice storage reservoirs program.
